Here we will see how we can take all numbers whose D7 and D1 bits are 0, using 8085.Problem StatementWrite 8085 program to take all numbers from an array whose D7 and D1 bits are 0. Numbers are stored from 8001, and the array size is stored at 8000. Store the result from 9000 onwards.DiscussionTo solve this problem, we will AND the number by 82H (1000 0010). If the result is 0, then the number is acceptable. If the bit position D7 and D1 are 0, then only the result will be 0.InputAddressData……80000A8001E98002D38003618004AD80052A80061F80075D8008A68009A9800A35…… Flow Diagram ProgramAddressHEX CodesLabelsMnemonicsCommentsF00021, 00, 80 LXI H, 8000Load the ...

To swap the contents of two strings (say s1 and s2) without the third.First of all concatenate the given two strings using the concatenation operator “+” and store in s1 (first string).s1 = s1+s2;The substring method of the String class is used to this method has two variants and returns a new string that is a substring of this string. The substring begins with the character at the specified index and extends to the end of this string or up to endIndex – 1, if the second argument is given.Now using the substring() method of the String class store the ...

Now let us see a program of Intel 8085 Microprocessor. In this program we will generate 00H and FFH alternatively.Problem Statement:Write 8085 Assembly language program to generate 00H and FFH alternatively.Discussion:The 00H and FFH are changed alternatively in each second. So we need one second delay. We have created delay subroutine to generate 1s delay.Note: Here for simplicity we are storing the numbers into memory. To show the numbers, we can use 7 – segment display and other display function for showing it into the display.Input:Here we are not providing any input.Flow Diagram:Program:AddressHEX CodesLabelsMnemonicsCommentsF000AFLOOPXRA AClear A registerF00132, 50, 80STA 8050HStore ...

These instructions are used to perform operations where data bits are involved, i.e. operations like logical, shift, etc. We can say that these instructions are logical instructions. In 8086, the destination register may or may not the Accumulator.Let us see the logical instructions of 8086 microprocessor. Here the D, S and C are destination and source and count respectively. D, S and C can be either register, data or memory address.OpcodeOperandDescriptionANDD, SUsed for adding each bit in a byte/word with the corresponding bit in another byte/word.ORD, SUsed to multiply each bit in a byte/word with the corresponding bit in another ...

Before getting into example, we should know what singleton design pattern is. A singleton is a design pattern that restricts the instantiation of a class to only one instance. Notable uses include controlling concurrency and creating a central point of access for an application to access its data store.This example demonstrate about How to use singleton class in androidStep 1 − Create a new project in Android Studio, go to File ⇒ New Project and fill all required details to create a new project.Step 2 − Add the following code to res/layout/activity_main.xml. In the above code, ... Read More
You can easily query MongoDB with “like”:db.yourCollectionName.find({"yourFieldName" : /.*yourMatchingValue.*/}).pretty();To understand the above syntax, let us create a collection with some documents. Here, we have a collection with the name ‘employee’. The query is as follows:> db.employee.insert({"EmployeeName":"John", "EmployeeSalary":450000}); WriteResult({ "nInserted" : 1 }) > db.employee.insert({"EmployeeName":"Carol", "EmployeeSalary":150000}); WriteResult({ "nInserted" : 1 }) > db.employee.insert({"EmployeeName":"James", "EmployeeSalary":550000}); WriteResult({ "nInserted" : 1 }) > db.employee.insert({"EmployeeName":"Jace", "EmployeeSalary":670000}); WriteResult({ "nInserted" : 1 }) > db.employee.insert({"EmployeeName":"Larry", "EmployeeSalary":1000000}); WriteResult({ "nInserted" : 1 })Now you can display all documents from a collection using find() method. The query is as follows:> db.employee.find().pretty();The following is the output:{ "_id" : ObjectId("5c6c0b2e68174aae23f5ef59"), ... Read More
The taglib directive declares that your JSP page uses a set of custom tags, identifies the location of the library, and provides means for identifying the custom tags in your JSP page.The taglib directive follows the syntax given below −Where the uri attribute value resolves to a location the container understands and the prefix attribute informs a container what bits of markup are custom actions.You can write the XML equivalent of the above syntax as follows −When you use a custom tag, it is typically of the form . The prefix is the same as the prefix you specify in ... Read More
JDBC provides support for almost all the SQL datatypes Whenever the JDBC driver receives a call from a Java application it converts the Java datatypes in it to the corresponding SQL data types. The conversion process follows default mapping.
